Optical Image of Sirius A &
B
Sirius A is the bright star in the middle of the
image. On the right, slightly below Sirius A, is the
optically faint white dwarf star, Sirius B. The dim
spikes of light are instrumental artifacts.(Credit: McDonald

Orbit of Sirius A and B
The relative positions of Sirius A (large filled
circle) and Sirius B (small filled circle) in the 50
year orbit are shown. Note that north is down, as
opposed to up in the Chandra and optical images.(Credit: Burnham's Celestial
